Definitions

  • Laser beam through the cornea of movement of the eye i.e. a movement of the point of penetration of the visual field line through the cornea follows. It is thus possible to compensate for movements of the eye during the operation by swiveling the ablation laser beam.
  • the tracking device has a first and a second deflection mirror, which are arranged such that, for example, the first deflection mirror deflects the ablation laser beam upwards or downwards and the second deflection mirror subsequently the ablation laser beam laterally deflected. Both deflecting mirrors are along the axis of each incident ablation laser beam linearly displaceable.
  • the development of the invention according to claim 9 includes sensor means for detecting the current position of the deflecting mirror, which are integrated in the respective drive. This ensures a space-saving design.

Abstract

Ce procédé (2) de correction des troubles de la vue par photoréfraction présente un dispositif (50) pour détecter la position d'un oeil (20) à un moment donné. Il comprend en outre un dispositif (8) qui suit un point de percée (16) d'un axe de référence (12) d'un faisceau laser d'ablation (10) à travers la cornée (18) d'un oeil (20) pendant le traitement, dans des positions variables d'un point de percée (26) d'une ligne de champ visuel (24) à travers la cornée (28). Ce dispositif peut par exemple comporter un miroir de déviation (38) suspendu à la Cardan et commandé par une unité de commande (52). En cas d'écart excessif entre la position du point de percée (16) et la position du point de percée (26), le rayonnement du faisceau laser (10) peut, de préférence, être interrompu.
